Abstract

Ekosistem terumbu karang merupakan salah satu ekosistem utama di wilayah pesisir dan laut yang memiliki peran yang sangat besar terutama dalam mendukung sektor perikanan dan pariwisata. Perairan pantai Harlen Kampung Tablasupa memiliki ekosistem terumbu karang yang baik dan potensial untuk dimanfaatkan demi peningkatan kesejahteraan masyarakat. Ironisnya, pada beberapa lokasi telah mengalami kerusakan akibat penangkapan ikan yang menggunakan bahan peledak (bom) maupun akar tuba. Oleh karena itu, perlu upaya rehabilitasi yang telah rusak salah satunya dengan transplantasi karang. Transplantasi karang merupakan teknologi memperbanyak koloni dengan memanfaatkan reproduksi aseksual karang secara fragmentasi dari suatu koloni karang. Transplantasi bertujuan untuk mempercepat regenerasi karang yang telah mengalami kerusakan. Metode yang digunakan adalah metode rangka besi yang menyerupai jaring laba-laba sehingga dikenal dengan Metode Spider. Kegiatan ini dilaksanakan oleh Pusat Studi Sumber Daya Kelautan dan Perikanan Universitas Cenderawasih dengan melibatkan beberapa mitra dengan dukungan pendanaan dari PT PLN (Persero) Unit Induk Wilayah Papua dan Papua Barat melalui Program PLN Peduli. Hasil transplantasi menunjukkan bahwa metode Spider sangat berhasil, dimana tingkat kelangsungan hidup mencapai 92%. Tingkat kelangsungan hidup tersebut diduga karena pemilihan lokasi yang tepat dan kemampuan jenis yang ditransplantasi dapat beradaptasi terhadap lingkungan perairan sekitarnya. Coral reef ecosystems are one of the main ecosystems in coastal and marine areas which have a very large role, especially in supporting the fisheries and tourism sectors. The coastal waters of Harlen Kampung Tablasupa have a good coral reef ecosystem and have the potential to be utilized for improving people's welfare. Ironically, several locations have been damaged by fishing using blast fishing and tuba roots poison. Therefore, rehabilitation efforts that have been damaged are needed, one of which is coral transplantation. Coral transplantation is a technology to multiply colonies by utilizing the asexual reproduction of corals by fragmentation of a coral colony. Transplantation aims to accelerate the regeneration of corals that have been damaged. The method used is the Spider Method. This activity was carried out by the Center for the Study of Marine and Fisheries Resources, University of Cenderawasih, involving several partners with funding support from PT PLN (Persero) Unit Induk Wilayah Papua and Papua Barat through the PLN Care Program. The results showed that the Spider method was very successful with a 92% survival rate. The survival rate is thought to be due to the selection of the right location and the ability of the transplanted species to adapt to the surrounding aquatic environment.

Abstract

The catch from fishermen in the Hamadi village is currently sold fresh at the beach or taken to the Hamadi Fish Auction Place (TPI) for sale. The most abundant catch is yellowfin tuna (Thunnus albacares). Based on interviews with the fishermen's wives in Hamadi Village, the main issues they face are a lack of skills and technology, as well as tools and materials for processing fish products. During the fish abundance season, the fishermen's wives sell fish at lower prices due to a lack of knowledge about fish product processing and limited raw materials. The target of this activity is the fishermen's wives in Hamadi Village. The proposed solution is to conduct training on making tuna chips using moringa leaves as an additional ingredient. The community service activity took place on August 14, 2024, and was attended by 15 participants. The methods used were socialization and training (demonstration). The outcome of this community service activity was that participants gained knowledge and experience about the process of processing yellowfin tuna into fish chips (80%).  Keywords: JAS Fishermen's wives; Hamadi; Chips Moringa; Tuna
